Paul, you, I and all have an Example to follow, and He is Jesus Christ. Anyone who knows the severity of punishment in changing the Word of Yahweh would realize without having to study the issue that Jesus would never have used any language in teaching His Good News other than the language of the Temple. It does not take a lot to understand this, but it is simple to argue it. Had Jesus Christ used Greek or Latin, He would have been called on it from the start by the Pharisees, the Scribes and the Chief Priest. Paul followed the Example of Jesus, and I try my best to do the same. God bless you.
I think Paul would have known those things in Hebrew grammar, too... he could have written Yahweh, but he never did... why not follow Paul's example? That's what I'm wondering...
